A hierarchical XML (eXtensible Markup Language) database is being developed by the New Millennium Program to assist in technology return on investment (ROI) analysis and technology portfolio optimization. The database contains mission requirements and technology capabilities, which are related by use of an XML dictionary. The XML dictionary codifies a standardized taxonomy and, in effect, begins defining a set of ontological relationships for space missions, systems, subsystems and technologies. The XML dictionary, and the taxonomies defined therein, will be submitted to NASA, DOD and commercial standardization bodies as a proposed standard. In addition to being used for ROI analysis, the database is being examined for use in project planning, tracking and documenting. This paper describes the motivation for the database project, the technical approach, the reasoning behind the selection of an XML based approach, the current state of the project, and future plans for this work.
